Synonyme. Sprengel has suggested, in the Index to his Syst. Veg., that glabr&ta is the epithet fitterfor this species than leevig&ta : glabrata signifies rendered, or become, bald; tevigata, renderedperfectly even in surface.

Spec. Char.,%c. Leaves ovate-lanceolate, subcordate at the base, nearly entire; glabrous on theupper surface; roughish upon the veins on the under one. {Willd. Enum. Suppl.) In Rcem. etSchult. Syst. Keg., a somewhat different specific character is quoted from Wiild. Wild. Baumz.,p. 81., the following: — Leaves ovate, acuminate, subcordate at the base, unequal there, nearlyentire, glabrous on both surfaces. Additionally to the specific character, it is stated as follows: —It is a large tree. Its leaves have 1—2 teeth at the tip. It is a native of Louisiana . To this kindseems to belong that Cdltis named C. americana, or Micocoulierde la Louisiane, cultivated in theParis Garden, which Poiret, in Encycl. Suppl., 3. p. 668., No. 10., has noticed to have its leavesmembranous, rough on both surfaces, yet nearly glabrous ; with the base with one side shorterthan the other, and narrower, and some leaves almost falcate.

Identification. Pursh FI. Amer. Sept., 1. p.200.; Roem. et Schult. Syst. Veg., 6. p. 307.

Spec. Char., 8,-e. A small straggling bush. Leaves ovate, acuminate, serrate with equal teeth;unequal at the base; downy while young, afterwards nearly glabrous on both surfaces. Flowers3 upon a peduncle. Fruit solitary, ovate, black. Indigenous to the banks of rivers in Maryland and Virginia, where it flowers in May. Pursh has seen the kind alive. ( Pursh FI. A. S.) Theplant was introduced by Lyon in 1812; and the name is in Loddiges’s Catalogue, ed. 1836 j but wehave not seen the plant there or elsewhere.

App. i. Species of Celtis half-hardy , or not yet introduced.

C. orienthlis Lin., R. Mai, 4. t. 40., and out fig. 1255.,isanative of the Himalayas , introduced in 1820. In foliage itresembles C. occident&lis; but we have only seen a verysmall plant of it, against a wall, in the Horticultural So-ciety’s Garden. In p. 174., five Himalayan species areenumerated as likely to prove hardy or half-hardy; butnone of them are yet introduced. In the Hortus Britan -nicus three species are enumerated as indigenous to Ja­ maica , and as, in Britain , requiring the stove ; but, as C.orienthlis is also designated as a stove tree in catalogues,it is possible that the Jamaica species may be equallyhardy. In the Himalayas , Royle observes, the genusCeltis occurs at considerable elevations, and as far northas Cashmere. C. orienthlis Wall., which we suppose tobe identical with C. orienthlis Lin., “ and species allied toit, occur in the hottest places; C. tetrandra Roxb. extendsalong the foot of the mountains as far as Cashmere .” C.alplna Royle was found by Mr. Royle on Urrutka, nearlyat the greatest elevation, and if it were introduced would,doubtless, be hardy in the climate of London . C. Ingl&sftRoyle occurs in Kunawur; and is, doubtless, equally hardywith C. alpfina As the seeds of Celtis go in little bulk,and retain their vital energies for at least a year, therewill be little difficulty, we think, in getting these speciesintroduced into Britain .

OF THE HARDY LIGNEOUS PLANTS OF THE ORDER JUGLANDa'cE*

The hardy ligneous plants of this order are included in the genera namedand characterised as under: —

Ji j'glams L. Flowers unisexual; those of both sexes upon one plant. —Male. Flowers in cylindrical, drooping, solitary catkins; many in a catkin:the catkins developed from buds borne by shoots produced previously tothe year in which the catkins appear. Calyx of 5—6 scales, that areattached to a bractea at a distance from its base and tip. (Is the flowerstalked, and connate with the bractea ?) Stamens 18—36.—Female. Flowerssolitary, or a few in a group, terminal upon a shoot developed in the sa® eyear. Calyx ovate, including and adhering to the ovary, except in the4-toothed tip. Petals 4, small, inserted into the free part of the cal}*'Ovary of one cell, and one erect ovule. Stigmas 2 —3, fleshy, scaly with
